Fair and hatch equation
WebIn science and engineering, hydraulic conductivity ( K, in SI units of meters per second), is a property of porous materials, soils and rocks, that describes the ease with which a fluid (usually water) can move through the pore space, or fractures network. [1] WebApr 18, 2024 · Groundwater modelling started with Darcy equation (1854), hydraulic conductivity relation (Fair and Hatch 1933), well response to pumping (Theis 1935) and correlation between ground water and precipitation (Jacob 1943, 1944). The groundwater area is highly developed, triggered by the digital revolution.
